If you were going to build a train line to Reynella / Morphett Vale etc, wouldn't it be cheaper to use the old rail corridor from Hallett Cove? It seems really expensive and almost pointless to build a brand new line. The line to Hackham via Hallett Cove would be 35km to ARS, only 3km longer than a direct route.

I'd rather see the Seaford Line extended to Aldinga and a new branch line from Elizabeth to Craigmore via Elizabeth Park and alongside Adams Road with stations at Fremont Park, Craigmore South, Craigmore

On the Flinders link upgrade... I thought part of the point of where they're planning to put the station is that they want to do some new development near the FMC carpark and this will add value to the project. Honestly the Tonsley line is not used much at the moment and adding this extension will make it much more viable, so I hope it happens soon, whatever exact route it takes. I don't buy the arguments about future extensions, I just don't see the line being extended any further in the next 50 years. The government isn't about to find the money to do lots of extending to the Adelaide network, and an extension in a hilly area to a residential population that has other train lines not too far away isn't going to be high up the list.

Also I sympathise with those with accessability issues, but train services shouldn't have stations every 500 metres. It's mass transit, not local door to door transport.... Hopefully if they rebuild Clovelly Park station one day they can move it slightly South, but other than that I don't think there's a need to keep Tonsley station if they're building a new one at Flinders.
